["Samarth Jain (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PHOENIX-4333?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Samarth Jain updated PHOENIX-4333:
----------------------------------
    Attachment: PHOENIX-4333_v1.patch

With this patch, we now detect that if we don't have stats information available for all the regions, then we report estimates as null. The updated test tests out this scenario.

[~jamestaylor], please review.
